# Description

# Root Zone Label Generation Rules for the Georgian (Mkhreduli) Script

## Overview

This file contains a set of Label Generation Rules for Georgian Mkhedruli (modern) for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Georgian Script Root Zone LGR” [Proposal-Georgian]. This file is one of a set of LGR files that together form an integrated LGR for the DNS Root Zone [RZ-LGR-6]. The format of this file follows [RFC 7940].

## Repertoire

The repertoire is described in Section 5, “Repertoire” of [Proposal-Georgian] and only includes the 33 code points used by languages that are actively written in the Mkhedruli alphabet.

The repertoire is contained in [MSR-6], which is a subset of [Unicode 16.0.0].

As part of the Root Zone, this LGR includes neither decimal digits nor the HYPHEN-MINUS.

Repertoire Listing: Each code point or range is tagged with the script or scripts with which the code point is used. For each repertoire element, one or more references document sufficient justification for inclusion in the repertoire; see the “References” below. For code points that are part of the repertoire, comments identify the language using the code point.

## Variants

According to Section 6, “Variants” in [Proposal-Georgian], this LGR defines no variants.

Additional Variants: This LGR inherits additional blocked cross-script variants by integration; they may not be listed here unless they result in in-script variants. See the merged, Common LGR [RZ-LGR-6] for details of all applicable cross-script variants, including any not listed here; always use the Common LGR for determining cross-script collisions of labels.

## Character Classes

This LGR does not define character classes.

## Whole Label Evaluation (WLE) and Context Rules

### Default Whole Label Evaluation Rules and Actions

The LGR includes the set of required default WLE rules and actions applicable to the Root Zone and defined in [MSR-6]. They are marked with ⍟. The actions compute a label disposition based on WLE rules or variant mapping types.

### Georgian-specific Rules

According to Section 7, “Whole Label Evaluation (WLE) Rules” in [Proposal-Georgian], this LGR does not define rules specific to Georgian.

## Methodology and Contributors

The Root Zone LGR for the Georgian (Mkhreduli) Script was developed by the Georgian Generation Panel. For details on methodology and contributors, see Sections 4 and 8 in [Proposal-Georgian], as well as [RZ-LGR-6-Overview].

Legend

Code Point
  A code point or code point sequence.
Glyph
  The shape displayed depends on the fonts available to your browser.
Script
  Shows the script property value from the Unicode Character Database. Combining marks may have the value Inherited and code points used with more than one script may have the value Common.
Name
  Shows the character or sequence name from the Unicode Character Database.
Ref
  Links to the references associated with the code point or sequence, if any.
Comment
  The comment as given in the XML file. However, if the comment for this row consists only of the code point or sequence name, it is suppressed in this view. By convention, comments starting with “=” denote an alias. If present, the symbol ⍟ marks a default item shared among a set of LGRs.

# Variants

This LGR does not specify any variants.

# Classes, Rules and Actions

## Character Classes

Implicit defined by script tag | 1

The following table lists all named and implicit classes with their definition and a list of their members intersected with the current repertoire (for larger classes, this list is elided).

Name | Definition | Count | Members or Ranges | Ref | Comment
--- | --- | --- | --- | --- | ---
implicit | Tag=sc:Geor | 33 | {10D0-10F0} |  | Any character tagged as Georgian

Legend

Members or Ranges
  Lists the members of the class as code points (xxx) or as ranges of code points (xxx-yyy). Any class too numerous to list in full is elided with "...".
Tag=ttt
  A named or implicit class defined by all code points that share the given tag value (ttt).
Implicit
  An anonymous class implicitly defined based on tag value and for which there is no named equivalent.

## Whole Label Evaluation and Context Rules

Number of rules | 1
Used to trigger actions | 1

The following table lists all named rules defined in the LGR and indicates whether they are used as trigger in an action or as context (when or not-when) for a code point or variant.

Name | Regular Expression | Used as Trigger | Anchor | Used as Context | Ref | Comment
--- | --- | --- | --- | --- | --- | ---
leading-combining-mark | `(start)[∅=[[\p{gc=Mn}] ∪ [\p{gc=Mc}]]]` | ✔ |  |  |  | Default WLE rule matching labels with leading combining marks ⍟

Legend

Used as Trigger
  This rule triggers one of the actions listed below.
Used as Context
  This rule defines a required or prohibited context for a code point C or variant V.
Anchor
  This rule has a placeholder for the code point for which it is evaluated.
Regular Expression
  A regular expression equivalent to the rule, shown in a modified notation as noted:
start or end
  (start) matches the start of the label; (end) matches the end of the label.
[\p{ }] - property
  Set of all characters matching a given value for a Unicode property [\p{prop=val}]. Note: uppercase “\P” defines the complement of a property set.
∪, ∩, ∖, ∆ - set operators
  Sets may be combined by set operators (∪ = union, ∩ = intersection, ∖ = difference, ∆ = symmetric difference).
∅= - empty set
  Indicates that the following set is empty because of the result of set operations, or because none of its elements is part of the repertoire defined here. A rule with a non-optional empty set never matches.
⍟ - default rule
  Rules marked with ⍟ are included by default and may or may not be triggered by any possible label under this LGR.

## Actions

The following table lists the actions that are used to assign dispositions to labels and variant labels based on the specified conditions. The order of actions defines their precedence: the first action triggered by a label is the one defining its disposition.

# | Condition | Rule / Variant Set |  | Disposition | Ref | Comment
--- | --- | --- | --- | --- | --- | ---
1 | if label matches | leading-combining-mark | → | invalid |  | labels with leading combining marks are invalid ⍟
2 | if at least one variant is in | {out-of-repertoire-var} | → | invalid |  | any variant label with a code point out of repertoire is invalid ⍟
3 | if at least one variant is in | {blocked} | → | blocked |  | any variant label containing blocked variants is blocked ⍟
4 | if each variant is in | {allocatable} | → | allocatable |  | variant labels with all variants allocatable are allocatable ⍟
5 | if any label (catch-all) |  | → | valid |  | catch all (default action) ⍟

Legend

{...} - variant type set
  In the “Rule/Variant Set” column, the notation {...} means a set of variant types.
⍟ - default action
  Actions marked with ⍟ are included by default and may or may not be triggered by any possible label under this LGR.

Note: The following variant types are used in one or more actions, but are not defined in this LGR: allocatable, blocked, out-of-repertoire-var. This is not necessarily an error.
